Re: Margaret Frederickson/1886/NY & MN

I just started doing my Fredricksen line - I have seen the name spelled many different ways - Fredericksen, Frederickson, Fredrickson, Fredricksen.My gg grandfather was August Fredricksen - married Margaret McNamara.I have some old letters - and the names Delia, Frances, Dell, Margaret and Nellie keep coming up.I'm wondering if you have any information on an August Fredricksen. (Fredericksen) from Denmark to MN.I believe he came from a somewhat large family. Thanks! Brenda
